ASUS Vivobook X540UA-DM437R RAM upgrade specifications

ASUS Vivobook 15 Series X540UA-DM437R laptop features DDR4-SDRAM memory upgrade specifications with one SO-DIMM slot available for expansion. Maximum RAM capacity reaches 12 GB total, combining on-board memory with SO-DIMM slot configuration. Compatible memory modules operate at 2133 MHz frequency. Upgrade slots accommodate standard SO-DIMM form factor modules for enhanced system performance and multitasking capabilities.

Additional Notes

• The presence of on board memory indicates that 4 GB of the total capacity is non removable and cannot be replaced if the modules fail.
• The hardware architecture creates an asymmetrical dual channel configuration which may lead to performance variations once the capacity of the second module exceeds the capacity of the soldered chips.
• System bandwidth is restricted by the 2133 MHz ceiling of the soldered memory even if a higher speed 2400 MHz or 3200 MHz module is installed in the available slot.
• The 12 GB limit restricts the upgrade path to a single 8 GB module because the remaining 4 GB is permanently integrated into the motherboard.
• Upgrading requires a single rank or dual rank SO DIMM module but prevents the use of quad channel configurations due to the single physical expansion slot.
• The motherboard design necessitates partial disassembly of the chassis to access the internal expansion slot for any hardware modifications.
• Memory latency and timing synchronization will default to the slowest common denominator between the fixed integrated memory and the user installed module.
